In the Symbiotic ecosystem, Resolvers are the enforcement and arbitration mechanism.
Their primary job is to manage the slashing process.
Symbiotic delegates this crucial and complex logic to Resolvers.
A Resolver is essentially an on-chain or off-chain entity (or a combination) that has the authority to tell Symbiotic's core contracts: This operator misbehaved according to the rules of the service they were securing. You must slash their collateral.
